Letters Patent No. 95,399, dated September'28, 1869.

The Schedule referred-to in these-Letters Patent and making part 0! the's ame.

To all whom it may concern Be it known that I, SAMUEL H. WILLIAMS, of the city of Baltimore, State of Maryland, have .invented a newv and usefulimprovement,.consiisting of an Air- Tight Stove for Burning Bituminous Coal; and I do hereby declare the following to be a full and exact description of the same, reference being had to the annexed drawings, making part of this specification, in Which- .Figure 1 is a. sectional view of my improvement on a vertical plane cutting it from front to back;

Figure 2, a.sectional view on a plane cutting the stove from side to side; and

Figure 3, a top view of the cast-iron base.

This invention relates to air-tightstoves for'burning bituminous coal; and I It consists in the combination and arrangement of the parts of which it is composed, as will be more fully described hereinafter. V A

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The bottom A of the stove, and its sides, as high up as the grates, should be'made of cast-iron, elliptical in form, and be so arranged as to receive a sheetiron body, B, with an air-tight joint where the two come together. I

Inside of r the stove, and resting upon its bottom plate, there is placed an ash-pan, O, which slides in between vertical flanges D, which rise up from the lll ase-plate, .upon which the grate E and coal-chamber rest.

The coal-chamber is of cast-iron, its front and rear sides coming in contact with the sheet-iron body of the stove, and extending up as high as the bottom for the opening of the pipe H.

From the front of this fire chamber there are castiron flanges projecting, which form openings, the one below being large enough to admit the ash-pan, the

other forming an aperture through which to pass the coal into said chamber.

Over both of these openings are fitted removable air-tight caps or covers G G, the one, G, which covers the opening for the ash-pan, having a register formed in it for the passage of air for the support of combustion, which closes nearly air-tight.

lhe spaces I 1 between the straight sides of the coalchamber and the elliptical ends of the sheet-iron body, form fines, one on each side of the stove, through which, when the damper H is closed, the draught will pass down from the top of the coal-chamber to the bottom,

and back around the plates which sustain the grate, and which form the sides of the ash-pan, under-plates K K, and up the pipe. or-flue L in the rear, as shown in figs. 2 and 3, a direct draught being allowed through the hole H by the opening of damper H.

As a consequence of the above-described arrangecase or body B, and base A, all constructed and arranged to operate substantially as andfo'r the purpose set forth. r

2. The base A, when constructed with the upright flanges D and plate K K, to form an ash-pit and flues, for directing the draught tothe flue L, when the damper H is closed, substantially as shown and s. H. WILLIAMS.
